ARE MEASLES Immunizations A 'RELIGIOUS Commitment'?
Are Measles Immunizations Religious? No—But the Exemptions Are Fueling a Public Health Crisis
Let's be honest: if you're asking whether the measles vaccine is a religious object, you're probably confusing it with a holy relic. Spoiler alert—it's not. The MMR vaccine is a triumph of modern medicine, not a sacrament. But the question, however misguided, touches on one of the most contentious public health debates of our time: the use of religious exemptions to opt out of life‑saving vaccinations. And in the years since this article was first published in 2019, that debate has exploded into a full‑blown crisis. Measles—a disease the United States declared eliminated in 2000—is back with a vengeance. Children are dying. Hospital wards are filling up. And the country is on the brink of losing its hard‑won elimination status. So let's set the record straight: vaccines are not religious. But the exemptions that allow people to refuse them? Those are a matter of law, politics, and—increasingly—life and death.
Back in 2019, the United States was reeling from the largest measles outbreak in nearly three decades, with 1,274 confirmed cases across 31 states. The epicenters were in New York's Orthodox Jewish communities, where misinformation about vaccine safety had spread like wildfire, and in Washington state, where low vaccination rates had created a tinderbox. Public health officials were scrambling. New York City declared a public health emergency, mandating vaccinations in four Brooklyn ZIP codes. Rockland County banned unvaccinated children from public spaces. Washington state lawmakers, facing a measles outbreak that sickened more than 70 people, passed a bill eliminating personal and philosophical exemptions for the MMR vaccine. It felt like a turning point—a moment when the country might finally get serious about closing the loopholes that were allowing preventable diseases to stage a comeback. But as we now know, it was only the beginning.
"Vaccines are not a religious issue. They are a public health issue. The question is whether we have the political will to protect our children from preventable diseases."
The 2025‑2026 Outbreak: A Crisis Three Decades in the Making
If 2019 was a wake‑up call, the years since have been a slow‑motion train wreck that finally crashed into the station in 2025. The numbers are staggering. In 2025, the United States recorded 2,285 confirmed measles cases—the highest total in 33 years[reference:0]. That's more than triple the 2024 total and represents the worst outbreak since 1991. And 2026 is on track to be even worse. Just three months into the year, there were already 1,575 confirmed measles cases across 31 states—more than half of the total for all of 2025[reference:1]. By mid‑April, that number had climbed to 1,748 cases[reference:2]. "It is likely that we will surpass last year's case count because we have a growing number of unvaccinated communities," warned Amira A. Roess, PhD, MPH, professor of global health and epidemiology at George Mason University[reference:3].
The geography of the outbreak tells a story of vulnerability. The 2025 outbreak began in West Texas in January, spreading through a close‑knit, under‑vaccinated community. By the time Texas declared its outbreak over in August, the state had recorded 762 cases, 99 hospitalizations, and two deaths in school‑aged children—the first measles deaths in the United States since 2015[reference:4]. But the virus didn't stop there. An outbreak along the Utah‑Arizona border, which began in August 2025, has continued into 2026, with Arizona documenting 222 cases in Mohave County and Utah confirming 216 cases[reference:5]. South Carolina has emerged as the new epicenter, with 664 cases in 2026 alone and more than 500 people in quarantine at one point[reference:6]. And the virus has popped up in ICE detention facilities in Texas and on college campuses in Florida, showing that no community is immune when vaccination rates fall[reference:7]. In all, the CDC recorded 49 measles outbreaks in 2025, up from just 16 in 2024[reference:8]. The map of infection looks like a patchwork quilt of vulnerability—and the threadbare patches are getting larger every year.
Globally, the picture is equally alarming. While Europe and Central Asia saw a 75% drop in cases in 2025—from 127,412 in 2024 to 33,998—the overall burden remains far above pre‑2020 levels[reference:9]. The Western‑Pacific region, including East Asia and Southeast Asia, reported 42,000 confirmed cases as of November 2025, a five‑fold increase from 2024[reference:10]. And measles continues to kill an estimated 95,000 people globally each year, mostly children under five[reference:11]. The virus hasn't gone anywhere; it's just been waiting for our defenses to drop. And drop they have.
The Immunization Gap: How We Lost Herd Immunity
Measles is one of the most contagious viruses on the planet. Its basic reproduction number—the average number of people one infected person will spread the disease to—is between 12 and 18. To put that in perspective, the original strain of COVID‑19 had an R₀ of around 2 to 3. Measles is so contagious that if one person has it, 90% of the people close to that person who are not immune will also become infected. The virus can linger in the air for up to two hours after an infected person leaves a room[reference:12]. This is not a disease you can dodge with good hygiene or a strong immune system. The only reliable protection is vaccination—and that protection only works if enough people are vaccinated to achieve herd immunity.
For measles, the magic number is 95%. When 95% of a community is vaccinated, the virus can't find enough susceptible hosts to sustain transmission. But the United States has been slipping below that threshold for years. During the 2019‑2020 school year, national MMR vaccination coverage among kindergartners was 95.2%—barely above the herd immunity threshold. By the 2024‑2025 school year, it had fallen to 92.5%, leaving approximately 286,000 kindergartners unprotected[reference:13]. That's 286,000 children who are essentially kindling, waiting for a spark. And the spark, inevitably, comes from international travel or an outbreak in a neighboring community.
The state‑level data is even more alarming. Only 10 states currently have MMR vaccination rates of 95% or higher[reference:14]. Fifteen states are below 90%, with Idaho at the very bottom at 78.5%—a rate more typical of a developing country than the world's wealthiest nation[reference:15]. Connecticut, by contrast, leads the nation at 98.2%, proving that high coverage is achievable when policy and culture align[reference:16]. The gap between Idaho and Connecticut is not a matter of geography or genetics; it's a matter of policy, politics, and public health infrastructure. And that gap is where measles lives.
The Exemption Explosion: Religious, Philosophical, and Conscience‑Based Opt‑Outs
So how did we get here? The answer, in large part, lies in exemptions. All 50 states require certain vaccinations for children to attend public school, but all states also allow medical exemptions for children who cannot be vaccinated due to underlying health conditions. The controversy—and the crisis—revolves around non‑medical exemptions. These are waivers that allow parents to opt their children out of required vaccinations for religious, philosophical, or "conscience" reasons. And they have been exploding in recent years.
During the 2024‑2025 school year, the rate of kindergarten students with a vaccine exemption hit a record 3.6%, up from 3.3% the previous year[reference:17]. Seventeen states now have exemption rates above 5%, and exemptions increased in 36 states and the District of Columbia[reference:18]. The vast majority of these exemptions are non‑medical. About 138,000 kindergartners were exempt from one or more vaccines last school year[reference:19]. That's a small army of unvaccinated children entering schools every year—each one a potential vector for a disease that can kill or permanently disable.
The legal landscape is shifting, but not always in the direction of public health. Some states are tightening their exemption laws. South Carolina is considering a bill to remove the religious exemption for the MMR vaccine for children attending public schools—a move that would align the state with the American Academy of Pediatrics' recommendation that only medical exemptions be allowed[reference:20]. Other states, like West Virginia, have introduced bills to create new exemptions for religious and philosophical beliefs[reference:21]. Florida is moving forward with a bill that would expand exemptions to include "conscience" objections, making it even easier for parents to opt out[reference:22]. And Health and Human Services Secretary Robert F. Kennedy Jr.—a longtime vaccine skeptic—has replaced members of the CDC's vaccine advisory group with people who have spread vaccine misinformation, sowing further distrust in the very institutions designed to protect public health[reference:23].
The irony is that most major religions have no prohibition against vaccination. The Vatican has stated that Catholics have a "moral obligation" to vaccinate. Orthodox Jewish authorities have repeatedly affirmed that vaccination is not only permitted but required under Jewish law. Protestant denominations overwhelmingly support vaccination. The only significant religious opposition comes from a small number of fundamentalist Christian sects and the Dutch Reformed Church, and even among these groups, the opposition is not universal. In other words, the vast majority of religious exemptions are not rooted in genuine theological doctrine. They are rooted in misinformation, fear, and a political movement that has conflated "religious freedom" with the right to endanger public health. "Vaccines are not a religious issue," Dr. Paul Offit, director of the Vaccine Education Center at Children's Hospital of Philadelphia, has said repeatedly. "They are a public health issue." And yet the exemptions keep piling up.
The Misinformation Machine: From Wakefield to RFK Jr.
If exemptions are the gasoline, misinformation is the match. The modern anti‑vaccine movement can trace its origins to a single fraudulent paper published in *The Lancet* in 1998, in which British physician Andrew Wakefield claimed a link between the MMR vaccine and autism. The paper was retracted, Wakefield lost his medical license, and dozens of subsequent studies involving millions of children have found no association whatsoever between vaccines and autism. And yet the lie persists. A 2026 scoping review in the *Journal of Pediatric Nursing* found that "MMR vaccine misinformation has been plagued by the retracted link to autism" and that "declining vaccination rates corresponded with circulating social media posts promoting misinformed beliefs towards the MMR vaccine"[reference:24]. The review also found that current communication interventions to combat vaccine hesitancy have "no impact"—meaning that once someone has been exposed to misinformation, it's extraordinarily difficult to change their mind[reference:25].
The COVID‑19 pandemic supercharged this dynamic. The politicization of COVID vaccines, the spread of conspiracy theories on social media, and the erosion of trust in public health institutions created a perfect storm. "I think that the COVID‑19 pandemic fueled, if you will, this so‑called medical freedom movement, which is, 'I'm going to make a decision that's best for myself and my family, independent of how it affects your family,'" Offit said[reference:26]. The result is a fundamental breakdown in the social contract that underlies herd immunity—the understanding that we get vaccinated not just to protect ourselves, but to protect the most vulnerable among us: infants too young to be vaccinated, cancer patients on chemotherapy, and people with compromised immune systems.
The problem has been exacerbated at the highest levels of government. Health Secretary Robert F. Kennedy Jr. has repeatedly made false or misleading claims about measles, including asserting that the U.S. has contained outbreaks better than other countries—a claim that social media users quickly noted deflects responsibility from the nation's own record‑breaking case counts[reference:27]. The CDC, meanwhile, has dramatically reduced its social media promotion of MMR vaccination, with no posts promoting routine childhood immunization since April 2025[reference:28]. The silence from the very institutions tasked with protecting public health is deafening—and deadly. As one public health expert put it, "We are fighting a two‑front war: against the virus, and against our own government."
"If we lose our measles elimination status, it highlights our failures as a country to use tried and true safe and effective public health methods to control a preventable disease."
The Elimination Status in Jeopardy: A Stain on the Nation's Public Health Record
In 2000, the United States achieved a milestone: measles was declared eliminated from the country. This meant that while imported cases still occurred, there was no sustained transmission of the virus within U.S. borders. That status is now in grave jeopardy. The Pan American Health Organization (PAHO) will review the U.S. and Mexico's measles elimination status in November 2026. If officials determine that a particular strain of the virus has circulated for more than 12 months, the country will lose its measles‑free status[reference:30]. PAHO has already revoked the elimination status of the Americas region due to ongoing transmission in Canada—a sobering reminder that elimination is not a permanent achievement but a fragile status that must be continuously defended.
"If we lose our measles elimination status, it highlights our failures as a country to use tried and true safe and effective public health methods to control a preventable disease," Roess said[reference:31]. The economic consequences would also be severe. Outbreaks disrupt schools, strain healthcare systems, and cost millions in containment efforts. During the 2018‑2019 outbreaks, the economic burden of a single measles case was estimated at $47,000 in public health response costs alone. With thousands of cases, the tab runs into the hundreds of millions—all for a disease that could be prevented with a vaccine that costs pennies to produce.
A Glimmer of Hope: The Fear‑Driven Vaccine Uptick
Amid the gloom, there is a faint glimmer of hope—and it comes from an unexpected source: fear. When measles arrives in a community, even some of the most vaccine‑hesitant parents have a change of heart. The health department in South Carolina saw a nearly 170% increase in MMR immunizations at free clinics in January 2026 compared to the year prior, and the state is close to declaring its outbreak over[reference:32]. MMR vaccines jumped 15% in Texas in 2025 before the state declared its outbreak over in August. Utah's health department has also recorded a bump in immunizations since summer 2025, a hopeful sign for the country's most active current outbreak[reference:33].
Stuart Simko, a pediatrician in Greer, South Carolina—bordering Spartanburg County, the epicenter of the state's outbreak—said he has been fielding multiple calls a week from hesitant parents. "They usually open with some version of: 'Hey, so I know that I've been against vaccines, but this measles is in our backyard. What do you think?'" he said[reference:34]. The conversations are delicate, requiring trust, patience, and a willingness to meet parents where they are. "For whatever reason, they have different information," Simko explained. Working through what they've been reading and hearing, and easing their particular concerns, is part of the process[reference:35].
This phenomenon—the "fear‑driven vaccine uptake"—is both encouraging and deeply troubling. It shows that minds can be changed, but only when the threat becomes immediate and personal. By then, it's often too late. Children have already died. Communities have already been ravaged. The goal of public health is to prevent these tragedies, not to react to them. And that requires a proactive, not reactive, approach to vaccination.
The Road Ahead: What Does 2030 Look Like?
If current trends continue, the United States in 2030 will look very different from today. We may have permanently lost our measles elimination status. We may see thousands of cases every year, with sporadic deaths in under‑vaccinated communities. The economic and social costs will mount. And the trust in public health institutions—already eroded—may be shattered beyond repair. But it doesn't have to be this way. The tools to reverse this trajectory already exist. The MMR vaccine is safe, 97% effective with two doses, and has been administered to billions of people worldwide[reference:36]. The question is not whether we have the tools; it's whether we have the will to use them.
That will requires action on multiple fronts. First, states must eliminate non‑medical exemptions. The American Academy of Pediatrics has been unequivocal: only medical exemptions should be allowed for school vaccine requirements[reference:37]. Five states already have such laws, and their experience shows that they work—vaccination rates are higher, and outbreaks are rarer. Second, we must combat misinformation with a sustained, evidence‑based communication campaign. The current approach—which relies on debunking myths one by one—is failing. We need to understand the psychological and social drivers of vaccine hesitancy and develop interventions that actually work. Third, we must rebuild trust in public health institutions. That starts with leadership that respects science, communicates honestly, and prioritizes the health of the public over political expediency.
Finally, we must recognize that vaccination is not just a personal choice; it's a social responsibility. As Offit put it, "You know that you care about your neighbor, knowing that you may be sitting on the bus next to somebody who can't be vaccinated because they're getting chemotherapy for their cancer or immune‑compromised for some other reason"[reference:38]. Herd immunity is a collective achievement, and it requires collective participation. When we allow exemptions to proliferate, we are not just making a choice for our own children; we are making a choice for everyone else's children, too. And those choices have consequences. In 2025, three children died of measles in the United States—the first measles deaths in a decade[reference:39]. In 2026, more children will die. How many more will it take before we decide that enough is enough?
The measles vaccine is not a religious object. It is a scientific triumph, a gift of modern medicine that has saved millions of lives. But the exemptions that allow people to refuse it are a matter of public policy—and public policy can be changed. The question is whether we have the courage to do so. Because every day we wait, the virus is spreading. Every day we wait, another child is put at risk. And every day we wait, we move one step closer to a future where measles is no longer a disease of the past, but a permanent feature of the present. That is not a future any of us should accept.
Key Takeaways: Measles, Exemptions, and the Public Health Crisis
- 2025 was the worst measles year in 33 years: 2,285 confirmed cases, 49 outbreaks, and three pediatric deaths—the first in a decade. 2026 is on track to be even worse, with 1,748 cases as of mid‑April.
- Vaccination coverage has fallen below the 95% herd immunity threshold: National MMR coverage among kindergartners is now 92.5%, leaving approximately 286,000 children unprotected. Only 10 states have coverage of 95% or higher.
- Exemptions are at a record high: 3.6% of kindergartners had a vaccine exemption in the 2024‑2025 school year, up from 3.3% the previous year. Seventeen states have exemption rates above 5%.
- The vast majority of measles cases are in unvaccinated people: 93% of cases in 2025 and 92% in 2026 were in unvaccinated individuals or those with unknown vaccination status.
- Misinformation is the root cause: The retracted Wakefield study linking MMR to autism continues to fuel vaccine hesitancy. Social media misinformation spreads faster than corrections, and the COVID‑19 pandemic eroded institutional trust.
- The U.S. is at risk of losing its measles elimination status: PAHO will review the U.S. status in November 2026. If a virus strain has circulated for more than 12 months, elimination status will be revoked.
- Fear is driving some vaccine uptake: South Carolina saw a 170% increase in MMR immunizations at free clinics during its outbreak. But reactive vaccination is not a substitute for proactive prevention.
- Major religions do not oppose vaccination: The vast majority of religious exemptions are not rooted in genuine theological doctrine but in misinformation and the "medical freedom" movement.
- Only five states limit exemptions to medical necessity: The AAP recommends eliminating all non‑medical exemptions. States with stricter exemption laws have higher vaccination rates and fewer outbreaks.
